I've made an executable file from my Python - OCR program (import pytesseract) using cx_Freeze. The resulting .exe works fine on my own machine. To test the program I made a zip-folder and shared it with some friends and colleagues on a share point.
Now there is the following problem with the executable. It seems like pytesseract isn't included in the executable / zip-folder.

Here is the ErrorLog:

The first lines are absolute clear. I've found some ideas to modify setup.py to include all imports in the executable created by cx_Freeze. Here is the latest version.

from cx_Freeze import setup, Executable

import os.path



PYTHON_INSTALL_DIR = os.path.dirname(os.path.dirname(os.__file__))

os.environ['TCL_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tcl8.6')

os.environ['TK_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tk8.6')



additional_mods = ['numpy.core._methods', 'numpy.lib.format']

additional_files = [os.path.join(PYTHON_INSTALL_DIR, 'DLLs', 'tk86t.dll'),

            os.path.join(PYTHON_INSTALL_DIR, 'DLLs', 'tcl86t.dll')]



options = {

    'build_exe': {'include_files': additional_files, 'includes': additional_mods}

    }



setup(options = options,

      name = "main" ,

      version = "0.1" ,

      description = "" ,

      executables = [Executable("main.py")])

pytesseract is a wrapper for Google's Tesseract-OCR Engine. In order that pytesseractworks, the Tesseract-OCR engine needs to be installed and one must be able to invoke the tesseract command as tesseract (this means that the Tesseract-OCR installation directory needs to be in the PATH).

I believe that pytesseract has been properly included in the executable but that the tesseract command does not work on the "other PC" (either Tesseract-OCR is not installed there or the Tesseract-OCR installation directory is not in the PATH there).

You need to tell the owner of the "other PC" to install Tesseract-OCR and to check that it can be started with the command tesseract from any location.

Another option would be to include the whole Tesseract-OCR installation directory in the frozen executable using the build_exeoption include_files (your variable additional_files) and to make sure that this included directory gets included in the PATH on the target PC, but this is probably not platform-independent and thus not recommended.
